Pectate hydrolases of parsley (Petroselinum crispum) roots.
The presence of various enzyme forms with terminal action pattern on pectate was evaluated in a protein mixture obtained from parsley roots. Enzymes found in the soluble fraction of roots (juice) were purified to homogeneity according to SDS-PAGE, partially separated by preparative isoelectric focusing and characterized. Three forms with pH optima 3.6, 4.2 and 4.6 clearly preferred substrates w...
متن کاملBiochemical Changes in Two Parsley (Petroselinum crispum L.) Varieties during Saline Stress
Parsley root has been used medicinally since ancient times for possible medicinal qualities including antioxidative, antimicrobial, laxative, antihy-perlipidemic, anticoagulant and antihepatotoxic (1). The parsley importance is attributed to its high vitamins content (mainly vitamins C), anti-oxidants, and some mineral elements such as iron, as well as volatile oils that play an important role ...
متن کاملProtective effects of celery (Apium Graveolens) on testis and cauda epididymal spermatozoa in rat
Dear Editor Infertility is one of the health problems that will have a negative impact on the individual, social and economic and is seen in 10-15% of couples (1). About 40 % of the issues involved with infertility are due to the man. Male sperm cells count nowadays has decreased dramatically in comparison with those who lived 50 years ago (2). Causes of infertility in men are included: oligozo...
متن کاملBiosynthesis of Sucrose and Mannitol as a Function of Leaf Age in Celery (Apium graveolens L.).
In celery (Apium graveolens L.), the two major translocated carbohydrates are sucrose and the acyclic polyol mannitol. Their metabolism, however, is different and their specific functions are uncertain. To compare their roles in carbon partitioning and sink-source transitions, developmental changes in (14)CO(2) labeling, pool sizes, and key enzyme activities in leaf tissues were examined. The p...
متن کاملThe modification in quality of parsley (Petroselinum crispum) by selenium and amino acids .
This research was conducted with the purpose of appraising the effect of Selenium (Se) and/or amino acid fertilizers (AA) on improving growth, physiology, and biofortification of parsley grown under high EC condition. Plants were foliarly supplemented with four levels of Se (0, 25, 50, 100 mgl-1) and/or two concentrations of AA (0 and 0.2%) three times with a week interval. The significantly in...
